WOOL-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 263,728, datedSeptember 5, 1882.

Application filed March 27, 1882. (No model.)

To-all whom it may concern Be it known that we, FREDERICK G. SAR- GENTandALLEN OSARGENT, of Graniteville, in the county of Middlesex and Stateof Massachusetts, have invented a new and useful Wool-Washing Machine,of which the following is a specification.

Our improvement relates to machines in which the wool is put into oneend of a bowl or tank into the scouring-liquid and gradually passed tothe other, from which it is taken and passed between squeeze-rolls toexpress the scouring-liquid; and it consists in providing a bowl inwhich a current can be maintained in such manner that the fiber fed intothe bowl will be submerged and carried forward to the discharge end anddeposited upon the carrier without the use of rakes or conveyers. Weaccomplish these objects by the mechanism illustrated in theaccompanyingdrawings, in which- Figure 1 is a longitudinal central section of awool-washing machine of our construction. Fig. 2 is a side elevation ofthe same; Fig. 3, a plan.

A is the bowl, provided withthe perforated false bottom b.

O is the carrier, operating over the perforated inclined apron 0. Thiscarrier is shown in the drawings as a slat endless apron; but otherforms may be used.

D is a deflecting-plate.

E is the exhaust-pipe, carried from behind the perforated inclined apron0 around outside of the machine to the centrifugal pump f. This pipe isperforated on its under surface in the part c, which is in the liquidbehind the inclined apron. The centrifugal pump f is provided with anarrow outlet, g, which extends the whole widthof the bowl, and is givensuch a direction as will force the current against the deflectorD,sothatwhen the pump is set in operation there will be a strong currentforced into the bowl at one end and an equal quantityof liquid suckedout from the other, sothat when the woolis fed in at the end a ofthebowl it will be first sucked down by the current moving under thedeflecting-plate D in advance of it, and then, when it gets below theopenin g g, forced forward with the stream driven forward by the pump.While being so forced forward the air among the fibers is driven out andthe fluid takes-its place, so that after the wool passes under thedeflector it will be so surcharged with the fluid that it will have butbe carried along with the fluid toward the carrier O by the currentproduced by exhausting the fluid from that end by the pump through thepipe 6, and as the wool reaches the spiked roll 0 it will be lifted ontothe slat-apron and itrises above the level of the fluid the liquid willflow from it, carrying part of the impurities and foreign matter fromamong it. Just before the wool passes into the nip of the rolls it isagain surcharged with the fluid, which is showered down upon it by theperforated tube h, which is kept supplied with liquid by the centrifugalpump H, driven by the pulley W. This pump is supplied through the pipe kBy this means the largest possible quantity of scouring-fluid issupplied just before the squeeze-rolls act on the wool, which issometimes found advantageous to carry out the foreign matter with thelarge outflow of fluid when the rolls nip it as it passes from the classof machines known as soaking tanks, to which this device especiallybelongs. The upper apron-roll, 0 is driven by the pulley 0 Thecentrifugal pump f is driven by the conebelt pulley f which is drivenfrom a reverse cone-pulley placed on some adjacent countershaft. Thedeflecting-plate swings on a shaft, 61, provided with a quadrant, 61held in any position desired by the binding-screw d G is a gate, placedunder the false bottom b to prevent the tube 6 from being supplied byacurrent from under the bottom I), which might flow through the iopenings in it, and thereby weaken the current above the bottom towardthe carrier end of the machine. This gate may be made to slide on thescrews 9 or to open and close in any other well-known manner. This gatecan be regulated so as to permit of a downward draft on the fluid abovethe bottom, if it be desired. As the current flowing over the falsebottom will carry the wool forward in it, and as the same current canbeproduced without regard to thelength of the bowl, and as no machineryis necessary tomove the wool forward in the bowl, the length andcapacity of the bowl can be increased to any extent desired withoutincrea'singits cost prolittle tendency to rise to the surface, but willcarried up toward the squeeze-rolls D D. As-

portionally or to great amount, and therefore a soaking-machine whichwill automatically forward the wool, without conveying-rakes or othermechanism, over the body of the bowl can be cheaply and easily produced,so that the wool may be permitted to soak for a great length of timewithout delaying other machinery, and much better work can be obtainedby the washingmachine, into Whichit next passes, because the dirt andgum will be thoroughly loosened by the preliminary soaking.

sis a scraper or doctor, which is placedabove the level of the fluid inthe tank and in close contact with the lower roll, D. This scraperprevents the greasy matter which the scouring-liquid takesjrorn thewool, and which floats on the surface, from adhering to the roll andbeing carried up by it to the wool, arid again deposited by it upon theroll and carried over into the next machine.

We are aware of the existence of machines in which a current is made tofeed substances forward in a tank. 9 Such operation we do not claim asourinvention.

What we claim as new andof our invention 1. The combination of the bowlA, provided with the perforated apron c, and the deflecting-plate D,with the pipe E, adapted to convey the fluid from the rear of the apronto the front of the machine, and the pump f, adapted to force thescouring-liquid against the wool as it passes into the machine and carryit under the deflecting-plate D, substantially as described.

2. The combination of the bowl A, provided with the perforated bottomb,perforated apron c, and gate G, with the exhausttube E, perforated inthe part c, and the pump f, substantially as and for the purposedescribed.
